specifications.
5.2 Power Efficiency
One of the main features of blade servers is enhanced power efficiency. The M610x achieves higher
power efficiency by implementing the following features:
•
User-configurable power options through the M1000e Chassis Management Controller (CMC)
(see the M1000e documentation online at
for further details)
•
Improved power budgeting
•
Voltage Regulator (VR) efficiency improvements
•
CPU VR dynamic phase shedding
•
Switching regulators instead of linear regulators
•
Closed loop thermal throttling
•
Use of DDR3 memory (lower voltage compared to DDR2)
•
Memory VR static phase shedding
•
BIOS Power/Performance options page
•
Active Power Controller (BIOS-based CPU P-state manager)
•
Ability to throttle memory
•
Ability to disable a CPU core
•
Ability to turn off embedded NICs or PCIe lanes when not being used
•
Energy Smart components at the M1000e chassis level to selectively enable more computing
performance with less power consumption.
5.3 Thermal Operating and Storage Specifications
The M610x thermal solution includes:
Optimized airflow impedance for individual blade and chassis level airflow balancing
Custom air baffling directs airflow through the components to maintain proper cooling
Custom designed heat sinks maintain CPU, DIMM, and board-level chip temperatures within
thermal design targets
Separate airflow cooling path for the two full-length x16 PCIe Gen2 slots.
Support for dual slot NVIDIA
®
GPU cards up to 250W.
Highly Optimized Fan Control Algorithm
o Base fan speeds are a function of hardware configuration and ambient temperature to
minimize airflow for a given environment.
o Component algorithms: CPU PID, DIMMs, HW Configuration, IOH, GPU, and External
Ambient.
o The highest fan speed request from the above algorithms is used to set the
appropriate fan speed for the blade.
o Ambient and HW Configuration sets the minimum – other algorithms increase fan speed
to maintain proper cooling.
